研究目的: |
本临床回顾性研究,从课题组2015年至202年接诊患者所收集数据进行分析。针对两种咬合模式(轻咬合接触和非咬合接触)对后牙种植体中长期负载的影响进行分析和比较。评估后牙种植体在不同咬合接触模式下的中远期临床效果,分析种植修复体的咬合接触状态与种植体机械并发症及种植体周骨吸收间的关系。 |

|
Objectives of Study: |
This clinical retrospective study analyzed the data collected from patients treated by the research team from 2015 to 2020. It analyzed and compared the impact of two occlusal patterns (light occlusal contact and non-occlusal contact) on the medium and long-term loading of posterior dental implants. It evaluated the medium and long-term clinical effects of posterior dental implants under different occlusal contact patterns and analyzed the relationship between the occlusal contact status of implant prostheses and mechanical complications of implants as well as peri-implant bone resorption. |
